Description
KAISERLICHESIMPERIAL
Der vorliegende Resonanzboden besitzt an seiner hinteren Seite eine durch den Bau des Rastes bedingte Anzahl starker, gebogener Streben, welche mit dem Rande des Resonanzbodens fest verbunden sind und vermöge ihrer Elasticität den Boden spannen. Jede Spannstrebe steht an zwei Stellen durch Stellschrauben mit dem Rast in Verbindung, so dafs der Resonanzboden nach Bedürfnifs vorwärts und rückwärts gestellt werden kann. Es soll hierdurch der Ton des Instrumentes stärker und anhaltender werden. Ferner soll der Vortheil erzielt werden, dafs, wenn die Instrumente an Schönheit und Kraft des Tones verloren haben, durch die Stellschrauben dem Boden die etwa verlorene Spannung wiedergegeben werden kann.The soundboard at hand has a soundboard on its rear side that was created by the Rastes conditioned number of strong, curved struts, which with the edge of the soundboard are firmly connected and because of their elasticity stretch the ground. Every tension strut is connected to the detent at two points by means of adjusting screws, so that the The soundboard can be moved forwards and backwards as required. It should through this the tone of the instrument becomes stronger and more persistent. Furthermore, the advantage should can be achieved that when the instruments have lost their beauty and strength of tone, the tension that has been lost can be reproduced on the floor using the adjusting screws.
Fig. ι stellt den Resonanzboden von der hinteren Seite dar. Derselbe hat acht Spannstreben a, deren Enden mit dem Rande des Resonanzbodens durch Schrauben b fest verbunden sind. Jede Spannstrebe zeigt zwei Bohrlöcher c für die einzusetzenden Stellschrauben. Die in die ' Spannstreben eingelassenen Eisenplatten d dienen dazu, ein Eindrücken der zweiten Stellschraube in das Holz zu verhindern. .Fig. Ι shows the soundboard from the rear side. It has eight tension struts a, the ends of which are firmly connected to the edge of the soundboard by screws b. Each tension strut shows two drill holes c for the set screws to be used. The iron plates d embedded in the struts serve to prevent the second set screw from being pressed into the wood. .
Fig. 2 stellt den Querschnitt des Resonanzbodens dar. α ist hier der eigentliche Boden, b die Spannstrebe und c der Steg des Resonanzbodens. Fig. 2 shows the cross section of the soundboard. Here α is the actual floor, b the tensioning strut and c the bridge of the soundboard.
Fig. 3 stellt den Querschnitt des Rastes mit eingeschraubtem Resonanzboden dar. α ist hier der Stimmstock, b der Resonanzboden, c die Spannstrebe, d eine Saite, e der Steg, f die Eisenplatte, g sind die mit dem Rast fest verbundenen Holzstücke, durch welche die Stellschrauben gehen! Stellschraube h zieht die Spannstrebe fest gegen die Stellschraube i. Fig. 3 shows the cross-section of the detent with the soundboard screwed in. Here α is the sound post, b the soundboard, c the tensioning strut, d a string, e the bridge, f the iron plate, g are the pieces of wood firmly connected to the detent, through what the adjusting screws go! Adjusting screw h pulls the tensioning strut firmly against adjusting screw i.
Fig. 4 stellt den Rast mit eingeschraubtem Resonanzboden von der hinteren Seite dar. Hier ist α die Spannstrebe, b sind die Stellschrauben und c ist der Resonanzboden.Fig. 4 shows the latch with the soundboard screwed in from the rear. Here, α is the tensioning strut, b are the adjusting screws and c is the soundboard.
